8. Micro optical imaging – Text, line art, gray scale images and multi-reflectivity images are
engineered into optical Write Once Read Many (WORM) media at high resolution (over
12,000 dpi). Difficult to simulate the printing resolution.
9. Micro-printing/nano-printing – Miniature lettering which is discernible under magnification.
Incorporated into fine line backgrounds or placed to appear as bold lines. Continues to
decrease in size as technology improves. Difficult to duplicate.
10. Moiré pattern (anti-scan/VOID pattern) – A new pattern formed by the super positioning
of two patterns who periodicities are not identical. Security designs can be developed so
that a scanner or copier will only display part of the pattern and/or word VOID or COPY
appears instead of the pattern.
11. Non-standard type fonts – Special type that is not available on the commercial market
and is reserved for security card use only.
12. Rainbow printing – A subtle shift of color across a document. Accurately designed
patterns cannot be easily copied. It is often used with a fine line or medallion pattern in
the background of a card.
13. Security code – High-resolution color printing systems print a security code within the
body of the color printed photo image. The code can be printed in a non-proportional font
that can imbed characters on the edge or bottom of the printed picture.
Inks – All inks offered must be completely compatible with card materials in the card solution
offered.
1. Chemically Reactive – Contains a security agent that is sensitive to chemicals, i.e., polar
and non-polar solvents and bleach, commonly used to alter documents. The chemical
reaction is for the ink to run, stain, and bleed to show evidence of document tampering.
2. Infrared fluorescent – Forms a visible image when illuminated with light in the infrared /
red visible part of the spectrum.
3. Infrared dropout – Forms a visible image when illuminated with light in the visible part of
the spectrum, but cannot be detected in the infrared region.
4. Metallic, pearlescent, and iridescent – Inks that fluctuate in brilliance depending on the
angle of illumination of the viewing. Difficult to mimic the luster and hard to copy or scan.
5. Metameric – The use of a pair of ink colors that differ in spectral composition but match
one another under certain lighting conditions. Under incandescent light that may appear
the same, but under colored light they appear as different colors.
6. Optically variable (color shifting) – This overt security ink can be printed as a semitransparent
or opaque color shifting security feature. Advanced multi-layer light
interference structures create noticeable, reflecting color shifts, i.e., gold to green, green
to blue, etc.
7. Phosphorescent – Contains a pigment that glows when exposed to a light source of
appropriate wavelength. The reactive glow decays after the light source is removed.
8. Tagged – Contains taggants or compounds that are not naturally occurring and that can
be detected using special equipment that reacts to electromagnetic energy identifying the
grouping or type.
